It can be tough to roll out a pre-configured environment if you don’t know what you’re doing. We’ll show you how to streamline your service options with Docker, so that you can scale in an agile, responsive manner.
Key Features
- Learn how to structure your own Docker containers
- Create and manage multiple configuration images
- Understand how to scale and deploy bespoke environments
Book Description
Making sure that your application runs across different systems as intended is quickly becoming a standard development requirement. With Docker, you can ensure that what you build will behave the way you expect it to, regardless of where it's deployed. By guiding you through Docker from start to finish (from installation, to the Docker Registry, all the way through to working with Docker Swarms), we’ll equip you with the skills you need to migrate your workflow to Docker with complete confidence.
What you will learn
- Learn to design and build containers for different kinds of applications
- Create a testing environment to identify issues that may cause production deployments to fail
- Discover how you can correctly structure and manage a multi-tier environment
- Run, debug, and experiment with example applications in Docker containers
Who this book is for
This book is ideal for developers, system architects and site reliability engineers (SREs) who wish to adopt a Docker-based workflow for consistency, speed and isolation of system resources within their applications. You’ll need to be comfortable working with the command line.
Joseph Muli is an experienced DevOps engineer. Over the years, he has built deep love for scripting and automation with Python. Currently his main areas of interest are monitoring, logging, and maintenance – the key data reference points in any configurable environment.Sie lesen das E-Book in den Legimi-Apps auf:

Preface
DevOps with Docker outlines the power of containerization and the influence this innovation has on development teams and general operations. We also get to understand what DevOps really is, the principles involved, and how the process contributes to product health, by implementing a Docker workflow. Docker is an open source containerization tool that makes it easier to streamline product delivery and reduce the time it takes to get from a whiteboard sketch of the business to a money-back implementation.
The book will provide knowledge of the following:
Lesson 1, Images and Containers, shows how Docker improved a DevOps workflow and the basic Docker terminal commands that will be used in this book. We will learn the Dockerfile syntax in order to build images. We will run containers from images. We will then version images and Docker hub and deploy a Docker image to the Docker hub.
Lesson 2, Application Container Management, explores the docker-compose tool and gives an overview of a multi-container application setup. We will then manage multiple containers and distribute application bundles. Lastly, we will network with docker-compose.
Lesson 3, Orchestration and Delivery, gives us an overview of a Docker Swarm. We will then use the Docker engine to create a Swarm and manage services and applications in a Swarm. Finally, we will scale services up and down to test for a real-world application scenario.
